I'd be really interested in seeing a default set of channels that either upon reboot your Tivo tunes into or that the user can set to tune to on a daily basis.
Most would see this as frivolous but here is why I'd like it.
If I could tell Tivo on a daily basis to tune to all of my local channels then when I get home around 5:15 if no tuner was required for recording, then I could switch to a local channel and still have 30 minutes of the news.
I notice that when I reboot, all tuners become set to one channel (not sure if this was the last channel I viewed, etc.). It'd be nice to have a set of channels to auto tune to (if not in use) for a reboot.
